If this is a style that wild man Bam Margera trusts, then you certainly know it's a style you can trust. The BSG II from Electric has a durable 6 base grilamid frame with a UVA/UVB protected lens shield, 5 barrel stainless steel hinges, and a nickel plated signature logo. With this kind of technology and extreme good looks, it's no wonder why these are Bam Margera's Signature Stunt Series sunglasses.
